The body requires of glucose in order to create ATP. Two hormones are responsible for controlling the concentration of glucose in the blood. These are insulin and glucagon. The diagram illustrates the principle of negative feedback control in action involving blood sugar levels. Diabetes Diabetes insipidus is a condition where excess urine is excreted caused by the sufferers  inability  to  produce  ADH and promote the retention of water. Diabetes Mellitus is another form of diabetes where the sufferer does not have the ability to produce sufficient insulin, meaning that glucose cannot be converted into glycogen. Anyone who has this condition usually has to take injections of insulin after meals and snacks to maintain their storage of glucose needed in emergencies.

Urinary System Two major functions: 1.      Elimination o     Removal of harmful wastes. 2.     Regulation o     Control and balance of several substances in the blood including water, acids and bases (pH), ions and salts The major organs of the system include: 2  kidneys:  filters blood, producing urine 2  ureters:  carry urine to urinary bladder 1  urinary bladder:  stores urine 1  urethra:  carries urine to the outside of the body Associated blood vessels: renal artery:  carries contaminated blood into the kidneys renal vein:  carries purified blood from the kidney, placing the blood back into circulation Kidneys main excretory organs of the body found on the back wall of the abdomen on either side of the spine just below the ribs basic filtering unit inside the kidney is the  nephr...

Homeostasis   is the process of maintaining a constant internal environment despite changing external conditions Ensures that the organs of the body operate within their normal limits thereby working efficiently Based on a   feedback   system Information is sent to a control center which directs the organ to react accordingly Two major control centers: 1.      Brain of the nervous system 2.      Glands of the endocrine system Several factors must be regulated including: 1.      Temperature 2.      Heart rate 3.      Respiratory rate 4.      Blood pressure 5.      Water balance 6.      Blood sugar levels. 7.   Detoxification Activity Organs involved Center of Control Temperature Skin Hypothalamus ...

DRINK WATER ON EMPTY STOMACH It is popular in Japan today to drink water immediately after waking up every morning. Furthermore, scientific tests have proven its value. We publish below a description of use of water for our readers. For old and serious diseases as well as modern illnesses the water treatment had been found successful by a Japanese medical society as a 100% cure for the following ... diseases: Headache, body ache, heart system, arthritis, fast heart beat, epilepsy, excess fatness, bronchitis asthma, TB, meningitis, kidney and urine diseases, vomiting, gastritis, diarrhea, piles, diabetes, constipation, all eye diseases, womb, cancer and menstrual disorders, ear nose and throat diseases. METHOD OF TREATMENT 1. As you wake up in the morning before brushing teeth, drink 4 x 160ml glasses of water 2. Brush and clean the mouth but do not eat or drink anything for 45 minute 3.. After 45 minutes you may eat and drink as normal. 4. After 15 minutes of ...

Multi-cellular organisms are too big and not all of their cells have contact with the external environment.  All organisms need to exchange substances with their environment - take in needed molecules and get rid of waste.  A uni-cellular organism can use the processes of osmosis, diffusion and active transport to transport substances in and out of the organism, which is in this case just one cell.  But as organisms increase in size, they need a specialized transport system to exchange substances between the internal environment and the external environment.  Interestingly enough, osmosis and diffusion are still the important mechanisms at the cellular level.

Endocrine gland Main hormone Function Pituitary gland Growth hormone (GH) • Controls growth Antidiuretic hormone (ADH) • Stimulates the reabsorption of water in the kidneys (osmoregulation) Follicle-stimulating hormone (FSH) • Stimulates the formation of egg follicles in the ovary & the formation of sperms in the testes. Luteinising hormone (LH) • Brings about ovulation Thyroid-stimulating hormone (TSH) • Stimulates the thyroid gland to produce thyroxine. Endocrine gland Main hormone Function Thyroid gland Thyroxine • Control growth • Controls the rate of metabolism Testis (plural : testes) Androgen • Stimulates the development & maturation of the testes • Controls the development of male secondary sexual characteistics Adrenal gla...

• Hormone = an organic chemical compound produced by an endocrine gland & is transported by blood to its target organ to obtain a certain response.  An endocrine gland is a ductless gland .  To synthesise & secrete hormones.  The hormones are secreted into the blood stream à reach all parts of the body. à only certain organ will respond ( target organ of the hormone) • Both nervous system & endocrine system are involved in the coordination of body functions. Nervous system – detecting changes in the external environment & obtains relatively quick responses. Some physiological activities occur over a long period of time (menstrual cycle, development of secondary sexual characteristics & growth) à cannot be regulated by nervous system.  • It is necessary to have an endocrine system to regulate them. The ES complements the NS in coordinating body activities.

Our ability to sense the five accepted categories comes from receptors on our taste buds. These tiny sensory organs appear mostly on the tongue, the roof of the mouth and the back of the throat. The sense of touch also plays a key role in the experiencing taste, as evidenced by the strong opinions on crunchy versus smooth peanut butter.   smell, too impacts our our tasting  abilities. Just ask anyone with a stuffed-up nose picking away at what seems to be a plate of bland food. In the mouth itself, though food scientists continue to discover new receptors and new pathway for gustatory impressions to reach our brain. Here are some taste sensations vying  for a place at the table as a sixth basic taste.

assakamualaikum... pertama sekali sy nak ucapkan selamat bercuti kepada semua pelajar dan guru2 yang boleh bercuti. apa khabar semua? semoga semua sihat sejahtera. gayanya cuti kali ini berteman hujan, tiap2 hari ada hujan...maha suci Allah telah tetapkan rezeki kita. sy sebenarnyasedang mencuba pamplet baru...cantik ke tak inilah hasilnya. nampaknya tak banyak benda nak ditulis. cuma ada satu peristiwa ngeri berlaku petang tadi, dlm perjalanan pulang dari mentakab...iaitu satu kemalangan jalan raya...tp tak berani nak turun tengok...moto hancur...ambulan kehulu kehilir sibuk je...semoga mangsa selamat...
